The utility model relates to the technical field of ground mat production, in particular to a ground mat cutting device facilitating continuous production. According to the technical scheme, the cutting device comprises cutting discs, a cutting frame and a cutting motor, a cutting shaft is rotatably installed in the cutting frame, the outer surface of the cutting shaft is slidably sleeved with a plurality of sliding sleeves, the outer surface of each sliding sleeve is fixedly sleeved with a cutting disc and a rotating bearing, and the outer surface of each rotating bearing is fixedly connected with a guide sliding block through a connecting rod; a guide sliding groove is formed in the top of the inner wall of the cutting frame, the guide sliding block is located in the guide sliding groove, an electric cylinder is fixedly installed on the rear surface of the cutting frame through a fixing frame, and the output end of the electric cylinder is fixedly connected with a moving plate. According to the utility model, the distance between the equally-divided cutting discs can be conveniently adjusted so as to adapt to different equally-divided cutting requirements of different ground mats, the adjusting time of the cutting discs is saved, and the influence on normal production of the ground mats is effectively reduced, so that the continuous production of the ground mats is facilitated.

The application relates to the technical field of terminal equipment, in particular to an electronic device and a shell device. The shell device comprises a middle plate and a first convex column, the middle plate is provided with a first through hole, the first convex column is fixed to the middle plate, and the first convex column has a first wall surface facing away from the middle plate; a connecting piece is fixed to the first convex column, the connecting piece has a second wall surface, the second wall surface is oppositely arranged and spaced apart from the first wall surface; a display screen is fixed to one side of the middle plate facing away from the connecting piece; and a first functional unit, the first functional unit comprises a connecting part, the connecting part is located between the first wall surface and the second wall surface, and the thickness of the connecting part in a first direction is smaller than the spacing between the first wall surface and the second wall surface in the first direction. When the first functional unit is installed, neither the middle plate nor the first convex column is prone to deformation, so that the flatness of the whole middle plate is good, the display screen fixed to the middle plate is prevented from being deformed or from generating light and shadow problems, the use effect of the electronic device is better, and the user experience is good.

This utility model discloses a double-sided heating melting device for adhesive blocks, including a frame and a heat conduction system mounted on the frame. A melting tank is provided on the frame. The heat conduction system includes a first heating component and a second heating component. The first heating component is adapted to heat and melt the bottom of the adhesive block and convey the melted adhesive to the coating device. The second heating component is located at the outlet of the melting tank. This utility model, by placing a second heating component at the outlet of the melting tank, heats the bottom and sides of the resin respectively through the first and second heating components, enhancing the melting capacity, ensuring the resin melts and is used as soon as possible, and preventing the resin from tipping over the baffle when reaching the resin outlet, thus affecting the normal operation of the entire device.

The utility model discloses a variable inductor with continuously adjustable inductance, and relates to the technical field of inductors. The two sides of the top of the base are provided with a first motor and a second motor respectively, the top of the base is connected with two frameworks, an induction coil is connected between the two frameworks, one side of one framework is connected with a first rotating disc, and one side of the other framework is connected with a second rotating disc. By arranging the lead screw, the threaded sleeve and the outer iron core, the lead screw is driven to rotate through the output end of the second motor, the threaded sleeve drives the third supporting barrel to move towards the second supporting barrel through guiding of the guide rod, the distance between the third supporting barrel and the second supporting barrel is changed, and the amplitude of opening the outer iron core by the connecting rod is controlled; and the distance between the outer iron core and the induction coil is further controlled, so that the inductance value of the induction coil is changed by changing the relative position of the outer iron core and the induction coil.

The utility model belongs to the technical field of hoisting machinery, and particularly relates to a spacing-adjustable horizontal wheel assembly which comprises a mounting frame, a fixing frame is fixedly mounted on one side of the mounting frame, two strip-shaped grooves are formed in the top surface of the mounting frame, wheel shafts are slidably mounted in the two strip-shaped grooves, and the two ends of the mounting frame are provided with horizontal wheels. Horizontal wheels are rotationally mounted on the outer side walls of the two wheel shafts correspondingly, the two horizontal wheels can be adjusted according to the distance between different rails, when the distance between the two horizontal wheels is adjusted, a motor B is started to drive a lead screw to rotate, and when the lead screw rotates, a threaded sleeve can be driven to move on the lead screw; when the threaded sleeve moves, the movable seat can be driven to move through the cooperation of the connecting rod and the fixed seat, and the movable seat moves to drive the wheel shaft to move, so that the positions of the horizontal wheels are adjusted, the distance between the two horizontal wheels is controlled, and the distance between the two horizontal wheels is matched with rails of different specifications.
